Problems solved by technology

However, in some specific working conditions, if a large amount of irrelevant information is provided to the operator, such as an increase in the number of alarms that are irrelevant to the current operation under certain working conditions, it will increase the workload of the operator, and may even interfere with the operator's understanding of the current situation. Judgment of the important state of the power plant, so it is necessary to optimize the management of the alarm signal, that is, alarm suppression

Embodiment

[0051] There are many kinds of alarms in nuclear power plants, and the functions and importance of different alarms are different. In order to avoid suppressing critical, important, or high-level alarms, the funnel principle is strictly applied in the design of alarm optimization management for importance screening.

[0052] The funnel principle a clearly states that the alarms associated with the accident guidance procedures of nuclear power plants cannot be suppressed. This kind of alarm has the characteristics of representing the signs or phenomena of the accident, and is directly used for the diagnosis and guidance of the accident, and at the same time indicates that the unit is in an emergency state.

[0053] The funnel principle b specifies that the system and equipment-related alarms required by the safe operation of nuclear power plants are not suppressed. According to the analysis of this method, the occurrence of such alarms indicates that the operation of nuclear p...

Abstract

For digitization alarm of a main control room of a nuclear power plant, the invention provides the principles and design method of alarm optimization (how to restrain alarm on suitable occasions). The method comprehensively considers the design requirements of a technology system, safety operation requirements of the nuclear power plant, instrument control achieving modes and the like to achieve safe, reasonable and effective retraining of digitization alarm, lowers work burdens of operation workers, reduces possibility of human factor errors, and improves safety and economy of the nuclear power plant.

Description

technical field [0001] The invention belongs to the design technology of a main control room of a nuclear power plant, and in particular relates to a digital alarm optimization design method of a nuclear power plant. Background technique [0002] For nuclear power plants that use digital instrumentation and control systems (DCS) and advanced main control rooms, the alarm system integrated with the digital human-machine interface monitoring and control system is more flexible, not limited by physical space, and the number of alarms can also be increased according to operational needs And detailed, so that the operator can obtain more information and guidance, which is conducive to the safe and stable operation of the power plant. However, in some specific working conditions, if a large amount of irrelevant information is provided to the operator, such as an increase in the number of alarms that are irrelevant to the current operation under certain working conditions, it will ...
